LONDON — Japanese bank Sumitomo Mitsui Banking Corporation Europe has signed a 20-year lease on 160,000 square foot of space in central London.

British Land, which is leading the development of the 100 Liverpool Street building, announced the deal on Tuesday. Sumitomo is taking three floors in the development, which is in London's financial district. The office is due to be completed in 2020.

Tim Roberts, head of offices at British Land, said in a statement: "SMBCE's decision to invest in Broadgate for the long term is not only a strong endorsement of London as a global city which remains attractive to international organisations as a place to do business but of the wider campus and 100 Liverpool Street."

Sumitomo's commitment is a boost to London's ambitions to remain a global financial centre post-Brexit. There are concerns that thousands of finance jobs could be lost post-Brexit if the UK loses passporting rights, which allow companies to sell services across the EU from Britain.
